ANTESKID DEVICE.

Application filed January 9, 1924. Serial No. 685,253.

VTo ZZ whom ffmn/ concern.'

lle it known that l, lVILLmM F. S'rAGGnns, a citizen of the UnitedStates, residing at Mannington, in the county of Marion and State of@liest Virginia, have invented certain new and useful improvements inAntisirid Devices, of which the following is 'a full, clear, and exactdescription.

The invention relates to antislzid devices for vehicle tires, and one ofthe objects of the intention is to provide a device of this characterwhich is readily adaptable to roads of different types.

Other objects of the invention are to provide a device of this characterwhich is inexpensive in manufacture, which is highly efficient on alltypes of roads, which may be quickly and easily applied to the tires,and which is not injurious tq'the tires.

@their and further ob'ects and advantages of the invention will beapparent from the following detailed description, when taken inconnection with the accompanying draivings; in which, t

liigure 2 is a transverse sectional View (alien on line 2---2 of Figure1.

Figure S is a plan vieu1 of the autislid device :illustrated in Figurel,

l*1 igure t is a detail sectional view taken on line .4;4 of Figure 3;and

Figure is a plan -vicw of an antiskid device for the front tires.

Referring to the drawings more in detail3 numeral l refers to the fellyof an antoniobile wheel, numeral2 indicates the rim, and numeral 3indicates the tire.

rlhe antislid device to be employed on muddy or sandy roads is indicatedgenerally by uuuieral 4f, and consists of a relatively long lcmgitudinalrod 5 which is pref erably trianglgilar in crosssection and which isslightly curved longitudinally to conform to the curvature of the tire,Formed integrul with the relatively long longitudinal rod 5 are threerelatively short transverse rods (5, and these relatively shorttransverse rods are also preferably triangular in crosssection and arecurved to conform to the transverse curvature of the tire. The threetransverse rods are preferably arranged at the ends and at the middle ofthe longitudinal red, Attaching eyes 7 are carried by each end of themiddle transverse rod and :these attaching eyes are, in the preferredconstruction, formed integral with the middle rod.

Attached to each of the eyes 7 is a quick detachable hook 8, and in theopposite end of one of these hooks is mounted a loop member 9, and tothis loop member is attached a metallic strip 10 which is bent to titabout and conform to the shape of the telly. rlhe opposite end of thismetallic strip'l()` is adapted to vreceive one end of a clamping devicereferred to generally by numeral 1l, and the opposite end of theclamping device is attached to the other quick detachable link 8 bymeans Vof a loop 12.

The clamping device per se forms the subject matter of a separate PatentNo. 1,529,558 dated March 10, 1925, and the construction of the clampingdevice will therefore be described in a more or less general way.

The clamping device 11 consists of two spaced walls 12, andpivotallymounted between and at one end of these walls is a bell-crank lever 15.v The bell-crank lever 13 has an operating handle 14, and the oppositeend of the lever is formed of spaced members between which is pivotallyattached a hook 15. withv an aperture adapted to receive a cotter pin1.6 when the device is inv clamped position.

In Figure 2 the clamping device is shown in clamped or operativeposition. To release the device it is only necessary to remove the Thishook is provided Cotter pin and swing the handle 14 to the Y right(Figure 2), whereupon the lower end of the bell-crank lever 13 will moveinwardly and upwardly and carry the hook 15 with it, thereby releasingthe strain on the device and permitting the quick removal of theentireapparatus or the antiskid element 1, as may be desirable.

It is preferred, though not essential, that the portion of the metallicstrip fitting about the felly should be wrappedwith some padding fabric,as indicated by numeral 20.

Figure 7 shows an antiskid device particularly adapted for the frontwheels. This i device consists of a longitudinal rib 21, which ispreferably triangular in cross-section as in the previously describedconstruction. And integral with this longitudinal rib is a relativelythin web of sheet metal 22 which iscurved to conform to the curvature otthe tire. The Web 22 is provided with apertures 23 which are adapted tobe engaged by the quick detachable hooks 8 in exactly the same manner aspreviously described. Y l

In accordance With the patent statutes, I have described what I non7believe to be the best embodiment of the invention, but I do not Wishtobe understood thereby as limiting myself or the scope oftheinventiom'as many changes and modifications may be made Withoutdeparting from the spirit of the invention; all such I aim to include in`the scope or' the appended claims.

Having fully described the invention, what I claim as new and desire tosecure by Letters Iatent is:

l. An antiskid device including a metallic rod adapted to extendlongitudinally ot' the tire, a plurality or" l'transversesrods carriedby the longitudinally extending rod, and means for attaching chains tothe ends of one oit the intermediate transverse rods, the

ends of the remaining transverse rods being free.

2. An antiskid device including a metallic rod adapted to extendlongitudinally of the tire, said rod curved to conform to the curvatureof the tire and triangular in cross section, three transverselyextending rods carried by said longitudinally extending rod, and meansfor attaching a chain to the ends of the central transverse rod, theends et the other transverse rods being free.

3. An antiskid device including a metallic rod adapted to extendlongitudinally of the `tire said rod being curved to conform to thecurvature of a tire and triangular in cross section, three relativelyshort transverse rods integral with the longitudinal rod and carried'ateach end and the middle thereof, said transverse rods being triangularin cross section and curved to conform to the curvature of the tire,eyes formed in the ends of one of said transverse rods, and an attachingvchain adapted to engage said eyes.
